Novel 4-(4-bromophenyl)phthalazine and phthalazinone derivatives connected through 2-propanol spacer to N-substituted piperazine residue were synthesized. All the new compounds were screened for their effect on beta-adrenergic blocking activity on the norepinephrine-induced precontracted aortic ring module. Most test compounds displayed appreciable beta-adrenolytic activity compared to propranolol as a reference standard. The results have shown that compounds 3a, 3d, 3e and 7c displayed appreciable inhibition of norepinephrine-induced aortic ring contraction.

Bromination of (4-benzylphthalazin-1-ylamino) phenol (1) with bromine afforded the bromophenol derivative 7, while condensation of the isomeric (4-benzylphthalazin-1-ylamino) phenol (2) or 7-(4-benzylphthalazin-1-ylamino)naphthalene-2-ol (3) with arylidenemalononitriles 8a-c in ethanol/piperidine solution afforded chromene derivatives 9a-c and 10a,b. Treatment of 7-(4-benzylphthalazin- 1-ylamino)-4-(p-methoxyphenyl)-4H-chromene-3-carbonitrile (9a) with triethyl orthoformate/Ac2O afforded ethoxymethyleneamino derivative 11. Condensation of 9a with DMFDMA/xylene gave chromenopyrimidine derivative 13, while treatment of 9a with Ac2O afforded the N-acetylimino derivative 14. The structures of the newly synthesized derivatives were confirmed by their elemental analysis and spectral data. The antimicrobial activities of some selected compounds were also studied and some of them were found to exhibit promising effects against Gram-positive and Gram-negative bacteria and fungi.

Chemical research careers are more diverse than they might first appear, as there are many different reasons to conduct research and many possible environments. , Recommanded Product: p-Isopropylbenzenecarboxaldehyde, and the best way to enjoy it and learn about it is performing experiments.Introducing a new discovery about 122-03-2, Name is p-Isopropylbenzenecarboxaldehyde, molecular formula is C10H12O, belongs to phthalazine compound. In a document, author is Kiasat, Ali Reza.

A simple, efficient, and high yielding one-pot protocol for the synthesis of 2H-indazolo[2,1-b]phthalazine-trione derivatives has been developed by three-component coupling of phthalhydrazide, dimedone and some aromatic aldehydes in ecofriendly neat conditions promoted by nano-gamma-alumina sulforic acid. This protocol avoids the use of expensive catalysts, toxic solvents and chromatographic separation. Also the proposed protocol was extended to the linear beta-diketone (acetylaceton) instead of cyclic diketone (dimedone). The generality and functional tolerance of this convergent and environmentally benign method is demonstrated. The nature of each step of the suggested mechanism for this condensation reaction is also identified through Density Functional Theory (DFT) calculations using B3LYP/6-31G** level of theory. It is shown that the first step is charge controlled; whereas the second one is controlled by frontier molecular orbitals. The H-1 and C-13 chemical shift values together with the structural parameters of the title compound have been also computed and the scaled values have been compared with the corresponding experimental NMR and X-ray spectra. As a result, the calculated spectroscopic data and optimized geometry show a good agreement with the experimental results. (C) 2012 Elsevier B.V. All rights reserved.
